EFC Block BI [ Block 1 / Block 2 / Block 1+2 / None ]
Selection of blocking binary input for earth fault overcurrent protection.
Default setting: None
EFC Trp BO [ Trp 1 / Trp 2 / Trp 1+2 / None ]
Selection of trip binary output for earth fault overcurrent protection.
Default setting: None
IGS
IGS> Lim [ mA ]
Threshold for ANSI 50GS - ground surge instantaneous overcurrent protection. Level in 0,1 mA.
Step: 0,1 mA
Range: 0,0 - 100,0 mA
0 = OFF, the ANSI 50GS - ground surge instantaneous overcurrent protection is disabled
Default setting: 0 mA
IGS> Del [ s ]
Delay for ground surge overcurrent protection.
Step: 0,1 s
Range: 0,0 - 600,0 s
Default setting: 10 s
IGS> T Lim [mA ]
Limit value for ANSI 51GS - ground surge time-overcurrent IDMT curve. It shifts the curve in current
direction. Level is indicated in % of NominMainsCurr.
Step: 0,1 mA
Range: 0,0 - 50,0 mA
0 = OFF, the ground surge time-overcurrent overcurrent protection is disabled
Default setting: 0 mA
IGS> T Del [ s ]
IDMT curve shape selection. IGS> T Del is the reaction time of IDMT protection for 100 mA ground
surge current.
Step: 0,1 s
Range: 0,1 - 20,00 s
Default setting: 1,0 s
IGS> T Curve
Selection of which curve will be used for ANSI 51GS: ground surge overcurrent.
IDMT: parametric curve, given by the IGS> T Del and IGS> T Lim parameters as described
in the chapter ground surge time-overcurrent protection.
Mod Inv: moderately inverse curve according to ANSI standard
Very Inv: very inverse curve according to ANSI standard
Ext Inv: extremely inverse curve according to ANSI standard
IECInv: moderately inverse curve according to IEC standard
IECVerInv: very inverse curve according to IEC standard
IECExtInv: extremely inverse curve according to ANSI standard
Default setting: IDMT
IGS Block BI [ Block 1 / Block 2 / Block 1+2 / None ]
Selection of blocking binary input for ground surge overcurrent protection.
Default setting: None
